Main Components Used Solar Panels, On-Grid Inverter, Net Meter Solar Panels, Batteries, Off-Grid Inverter Solar Panels, Hybrid Inverter, Batteries
Best For Homes with stable electricity & lower budget Remote areas or frequent outages Homes wanting savings + backup

12) What is an On-Grid Solar System?

An On-Grid Solar System is connected directly to the local electricity grid. It generates solar power during the day and supplies it to your home or business. Any excess power produced is exported to the grid through net metering, helping reduce your electricity bill.
This system does not provide backup during power cuts, but it is the most cost-effective option for areas with reliable electricity supply.

13) What is an Off-Grid Solar System?

An Off-Grid Solar System operates completely independent of the electricity grid. It stores solar energy in batteries, which are used during the night or power outages.
This system is ideal for remote locations or areas with frequent power cuts where grid power is unavailable or unreliable. It ensures uninterrupted power but comes at a higher cost due to battery requirements.

14) What is a Hybrid Solar System?

A Hybrid Solar System combines the features of both on-grid and off-grid systems. It uses solar power during the day, stores excess energy in batteries for backup, and can also draw power from the grid when needed. This system offers the flexibility of power backup along with reduced electricity bills, making it a smart choice for homes and businesses that want reliability and long-term savings.

15) Can residential customers get solar subsidy under the PM Surya Ghar Scheme?

Yes. Residential customers are eligible for solar subsidy under the PM Surya Ghar (Muft Bijli Yojana) scheme, provided they install an on-grid solar rooftop system using approved components.


Subsidy Details:
• Up to 1 kW: ₹30,000

• Up to 2 kW: ₹60,000

• From 3 to 10 kW: ₹78,000 (maximum subsidy limit)

• Above 3 kW: No additional subsidy applicable


Important Conditions:

Subsidy is available only for on-grid systems

• Off-grid systems are not eligible

• DCR (Made-in-India) solar panels and inverters which are approved by local utility provider must be used

Installation must follow government-approved guidelines


LightLeader Support: LightLeader assists customers with eligibility checks, system design, DCR-compliant components, documentation, and complete solar subsidy coordination with BESCOM and other utility providers.

16) What is DCR and Non-DCR in Solar Systems?

DCR (Domestic Content Requirement): - DCR means the solar panels used in the system are manufactured in India using locally produced solar cells and modules.
These panels are mandatory for government subsidy schemes, including the PM Surya Ghar Yojana.

Required for subsidy

Approved by the Government of India

Supports Indian manufacturing

17) Can commercial or industrial rooftop customers get solar subsidy?

No. Commercial and industrial (C&I) rooftop solar systems are not eligible for government subsidyunder the PM Surya Ghar (Muft Bijli Yojana).


The subsidy scheme is exclusively meant for residential consumers installing on-grid rooftop solar systems.


However, commercial and industrial customers can still benefit through:

Significant electricity cost savings

Accelerated depreciation and tax benefits (as applicable)

Lower operational costs over the system lifetime

Net metering benefits (subject to DISCOM rules)

18) What costs are covered in LightLeader’s solar installation proposal?

LightLeader’s proposal includes end-to-end solar installation, covering:
Site visit and technical assessment

System design and engineering

Structural work (if required)

Supply of solar panels, inverters, mounting structures, and accessories

Complete installation and commissioning

Support for DISCOM approvals, net metering, and documentation


This ensures a smooth, hassle-free solar installation from start to finish.

19) Can an on-grid solar system be upgraded to add batteries later? 

Yes, many on-grid systems can be upgraded to hybrid systems if the inverter and system design support battery integration. Planning this early helps reduce future upgrade costs.

20)    How long does it take to install a grid-connected solar system? 

Physical installation of a 5 kw system typically takes 1 week time, provided there are no challenges in accessing and transporting materials to the installation site, while grid approvals and net-metering permissions may take a few weeks depending on DISCOM utility processes. 

21) What are the benefits of installing Solar PV rooftop system?

Installing a solar PV rooftop system increases your property’s market value, significantly reduces electricity bills, and protects you from future power tariff hikes. It transforms your rooftop into an income-generating asset while lowering your carbon footprint, supporting green building standards, and promoting long-term sustainability with reliable energy savings.
